I’ve always used double opt-in for my lists before but have decided to give single opt-in a try. When I first started in internet marketing with my health niche several years ago everyone was saying it was best to use double-opt-in. I signed up with Aweber’s auto-responder service for my list management and they seemed to be insisting on it.
If you don’t know what I am talking about I’ll explain.
When you are building an email marketing list it’s usual to give something away ( lead magnet) on a squeeze page in exchange for people’s email addresses. When a visitor enters his name and email address in the form he “opts-in” to receive your gift and further email messages from you.
